The 12:22 Roof Run and the Vanishing Limp (Claims)
:::caution Attributed claims only A limp that comes and goes is ordinary. It can be an affected gait, a transient strain, a cramp that works itself out, or an artifact of watching a distant figure on low-frame-rate rooftop video. The entry below carries no cited source, and "no longer noticeable" is an observer's impression, not a gait analysis. Tyler Robinson is charged, not convicted. :::

| The claim | The roof figure limped visibly all morning, then at 12:22 stood, ran west across the roof, and scooted near the edge with the limp "no longer noticeable" |
| Exact time in window | 12:22 PM MT — roughly 90 seconds before the shot |

What is alleged
The investigation file's compiled timeline of the alleged shooter's movements describes a limp appearing repeatedly across roughly half an hour. At 11:50 a.m. MT the figure reportedly reappeared walking in a grassy area north of Campus Drive near 800 West, "walking with a limp (stiff right leg, slow pace, limited bending)." At 12:02 p.m. he was reportedly seen walking on the north side of the Losee Center, "still limping," entering the building through the southeast corner doors. At 12:15 p.m. he reportedly climbed the stairs toward the roof, crossed a railing from a public walkway, ran across the roof, and crawled into a shooting position.
The entry that draws attention is the one for 12:22 p.m.: he "stood up and ran across the roof toward the west side, scooting near the edge (limp no longer noticeable)," then "laid down facing the courtyard area in a position ready to fire, approximately 430 feet (130 m) away." That parenthetical — three words — is the whole of the claim.
Investigators who raise it argue that a stiff right leg with limited bending, observed across three separate sightings over thirty minutes, does not simply resolve in the seven minutes between 12:15 and 12:22. Some connect it to the file's separate argument that the figure captured in the campus stairwell footage and Tyler Robinson are two different people — the reasoning being that a gait that changes may indicate the person changed. That argument is made elsewhere in the file on entirely different grounds (backpack fullness, clothing, the size of the rifle), and it is not established here.
What must be said plainly: the file cites no source for this timeline. There is no link to the surveillance footage, no charging document quoted, no named investigator, and no description of who watched the video or what resolution they watched it at. The words "no longer noticeable" describe what someone thought they saw. They are not a measurement.
The ordinary explanation
A limp is one of the least reliable things to read off distant video, and one of the easiest things to lose. A person favoring a leg because of a cramp, a rolled ankle, a blister, or a strain will often move normally once adrenaline arrives — pain suppression under acute stress is well documented and does not require any explanation beyond human physiology. If the gait was affected in the first place — deliberately assumed to look unremarkable while walking across a campus in daylight — then it disappearing at the moment concealment stops mattering is exactly what one would expect, and it argues for the same person rather than against him.
The observational problem is worse than the physiological one. The 12:22 movement is described as running and scooting near the edge of a roof, which is not walking at all. There is no normal gait to compare against, because the subject is crouched, moving laterally, and staying low. Campus surveillance video is typically low frame rate and heavily compressed; a stiff leg that is obvious in a slow walk at close range is invisible in a crouched scramble at distance. "No longer noticeable" may mean nothing more than that the conditions for noticing it were gone.
What would settle it
- Obtain the underlying UVU surveillance footage for 11:50 a.m., 12:02 p.m., and 12:22 p.m. and have a gait analyst — not a viewer — compare the three.
- Identify the source of this compiled timeline. Is it a charging document, a press briefing, or a secondhand summary of one?
- Establish the frame rate and resolution of each camera, which determines whether a gait could be read at all.
- Ask whether any medical record, injury, or condition explaining a stiff right leg exists for the charged defendant.
Sources
- No primary source or URL is cited in the investigation file for this timeline. It appears as a compiled minute-by-minute list, apparently paraphrasing law-enforcement-attributed reporting, with no attribution and no link.
